So what is the standard for fetal development at 16 weeks of pregnancy?

Fetal growth indicators at 16 weeks gestation.

The fetus is about 16 cm long from head to hip and weighs about 110 grams. The mean of the double parietal diameter is cm, the mean of the abdominal circumference is cm, and the femur length is cm.

The baby's arms and legs are fully developed, the joints are moving, the head is hairy, the stomach is secreting digestive juices, and the kidneys are secreting urine. Now the circulatory system and urethra are fully functioning, the baby's lungs are working, and he is able to inhale and exhale amniotic fluid continuously.

What's even more surprising is that during the week you feel more pronounced fetal movements, and sometimes some tenderness, which are normal reactions and don't worry.

Nutritional recommendations for fetal development at 16 weeks of pregnancy.

Now is the period when the fetus has tooth roots, and you should eat more calcium-containing foods to let the fetus grow strong tooth roots. In addition, white sugar has the adverse reaction of consuming calcium, and it is easy to make people fat. You can use brown sugar instead of white sugar.

At 16 weeks of pregnancy, the fetus develops very quickly, by this time the fetus already has some hair, and the fetus can also perceive some things in the outside world.

It is basically formed, and if it is quiet, the pregnant woman can feel a slight fetal movement.

The development of the fetus at this stage is particularly fast, and its facial features can be clearly seen, and their limbs can also be seen, which can judge the growth of the child.

For pregnant mothers, their bodies have also begun to show very obvious changes. As the fetus grows strongly, the pregnant woman's abdomen will become more and more prominent, and the change in body shape will make the pregnant woman also enter the embarrassing period of dressing. Ordinary clothes will be tighter on the body, more revealing the bulging abdomen, 16 weeks pregnant, that is, about 4 months, I feel that this month is the most comfortable time for pregnant mothers.

Why? Because at this time, most pregnant mothers no longer have the first trimester reaction in the first trimester, nor will they have the feeling of inconvenience and discomfort caused by a big belly in the third trimester.

In the second trimester, it is generally about 13 weeks to feel that the sky is bright after a night, and the world becomes better, usually get up at 8 o'clock because I want to vomit, and suddenly wake up at 7 o'clock after the second trimester, and I don't feel like I want to vomit at all, and my spirit still feels good. At 16 weeks of pregnancy, the baby will be very happy, he can also make a variety of movements, such as stretching legs, squinting, and even turning his heels, etc., and what is particularly exciting is that we can hear the fetal movement for the first time, which is also our most direct proof of the existence of the baby.

At 16 weeks of pregnancy, the baby has entered a small peak period of development, and now he has clear facial features, fully differentiated limbs, and obvious reproductive differentiation. At this time, the baby gradually grows up, and the fetal movement is slowly perceived by the mother. The uncomfortable morning sickness in the first three months gradually disappeared, my appetite was much better, and I didn't feel uncomfortable when I ate a little food in the later stage, and I didn't have any nasty stretch marks, edema, and chest tightness in the third trimester.

At 16 weeks pregnant, the mother has entered the middle pregnancy period, and this time period is a more comfortable thing for the mother. At this time, most mothers no longer have to worry about being afraid, after all, after the fetal teratogenicity period, they are far away from the hateful morning sickness reaction, and their appetite has improved, and they can happily eat a meal.

At this stage, the fetus is actually fully developed, and it is not much different from the normal baby shape.

At 16 weeks of pregnancy, the bones are fully developed, and the general condition of the fetus can be clearly seen, and the fetus will also have some fetal movements.
